Android:如何找到屏幕的宽度和高度？

Question

我试图找到屏幕的宽度和高度,但我尝试的方法都没有在我创建的类中工作,我的代码如下.

有谁知道如何找到它？我不能使用我在下面尝试的方式,因为.getWidth()已被弃用？

public class Crate {

    public int acrossCrate;
    public int upDownCrate;
    Context theContext;

    WindowManager wm = (WindowManager)theContext.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    int width = display.getWidth();


    public Crate() {
    acrossCrate = 650;
    upDownCrate = 650;
    //int width = ;
    //int height = ;

  }
 }

使用以下代码

private int getScreenHeight(Context context) {
        int height;

        if (android.os.Build.VERSION.SDK_INT >= 13) {
            WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = wm.getDefaultDisplay();
            Point size = new Point();
            display.getSize(size);
            height = size.y;
        } else {
            WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = wm.getDefaultDisplay();
            height = display.getHeight();  // deprecated
        }

        return height;
    }
